Get redy to feel the TORQUE !!!!
I was deciding between the V-force2 or Boyeyen .so i got em both ..after trying em i fond that the Boyesen rad valve is better if ur a trail rider b-cuz it give way more torque than the v-force . but if u are only concerned about top end speed , then the V-force is better b-cuz it gave alot better top end speed, but the boyesen has duel stage reeds..so she gave better throttle responce. so there you go the best of both and it all comes down to are you a trail rider or a racer . :) your welcome

Excelent value
Installed it on my CR-125 and what a difference....
I jetted down from the stock 172 main jet to the recommended 165 and the bike runs better than it ever did...plenty of low end now, I can come out of a berm in 2nd gear now instead of having to grab 1st to get the jump on the dude next to me..:)

Pull hard in the mid range also ...no change in top end for me... but I didn't really expect any there
worth every penny I paid

great buy
Awsome and instant power, when u compare this valve to the stock veed cage it just looks like it has better flow. then when u put it on.. instant power. need to lean out the jets 1-3 sizes but other then that it fit perfect for my 01 cr250, all aluminium means it replaces that cheezy plastic stock reed cage which is prone to cracking and sucking in sand and dirt and killing your engine. great but looks great and performs better. Fast shipping and great service on this hard to find part for my bike thanks denniskirk and boyesen

AMAZED AT QUALITY
This is how parts should be made! This product is better than I could have expected. Now if only stock products were made with this quality. Solid piece of gear that fits perfect. Dual reeds was an added plus also. This is wayyyyy better then the multi piece stock part. I would not only recommend this product and company but its the only place I will buy from because of the bad a** quality and price of products! THANKS DINNIS KIRK!!!!!!!
